* Initial revision of fail2ban sensor
* Verified working, added tests
* Re-factored code so that log reading isn't called for each sensor
* Lint fixes
* Removed errant reset of last ban, added test to verify bans persist through update
* Removed for loop in read_log and replaced with regex per review request
* Refactored update to use current ban array for last ban state
- also was missing return False in timer for default behavior
* Removed CONF_SCAN_INTERVAL from PLATFORM_SCHEMA.extend
- renamed DEFAULT_SCAN_INTERVAL to SCAN_INTERVAL
* SCAN_INTERVAL changed to timedelta
* Force travis rebuild (last build timed out)
* Using compiled regex now
